  Bug #25176  	Trying to set ndb_autoincrement_prefetch_sz always fails: Changed pointer to max value
  Bug #31956  	auto increment bugs in MySQL Cluster: Changed meaning of ndb_autoincrement_prefetch_sz to specify prefetch between statements, changed default to 1 (with internal prefetch to at least 32 inside a statement)
